Being familiar with Concrete Efflorescence How It Results In Ugly Foundation Walls
At Permaseal, we all answer customer questions regarding concrete issues every single day. Just about the most frequent, and most perplexing for home owners, is what they ought to do once they find layers of white-colored, flaky residue on their basement wall surfaces. This powder is very popular on cement types of surface -- particularly in cellars and crawl spaces -- and it is generally known as efflorescence.
What Can Cause Efflorescence?
Concrete is a permeable material -- and it has been since the day it dried. For this reason, it will take moisture from the ground outside, progressively releasing some of this moisture into your home. This is one of the primary reasons that cellars are infamously damp, humid areas.
As this moisture passes through your concrete, it brings a small portion of minerals from the soil outside in conjunction with it, along with the lime in the cement itself. When it evaporates into your cellar, it leaves these kinds of minerals behind. Over time, they create the white-colored, flaky powder that you see on your walls right now.
Cleaning Efflorescence from Basement Walls
There are several products currently available that are especially intended for getting rid of unsightly stains from concrete walls and floors. One good way to remove efflorescence is to rent a pressure washer from a nearby home improvement store and to combine it with these types of chemicals to successfully blast efflorescence off the cement.
For a less expensive solution, however, you could substitute these custom made chemical substances using a solution of bleach. Combined with a power washer, pressure washer, or just by applying with a scrub brush and some effort, you will be competent to clean off most efflorescence issues.
Phosphoric acid can also be used not only to eliminate efflorescence powder but also corrosion, grime, unsightly stains, and hard water build up. However, phosphoric acid, along with other chemicals, should be used very carefully and with great care.
Safeguarding Your Basement from Efflorescence
At Permaseal, we recommend protecting your cement areas from efflorescence before an issue arises. However, if you thoroughly clean already damaged concrete, protection can be applied after.
Our encouraged way to prevent efflorescence is by sealing your concrete walls with a concrete sealer. The product works deep in the pores of your cement walls and floor surfaces to create a glass-like silicate bond in the cement.
This barrier prevents the movement of moisture through the basement walls and floors, protecting your basement from both efflorescence and the water vapor transmission linked to basement moisture.
Concrete treatments can be applied as a spray, roller, paint brush, and also other ways, and it dries out in 2-4 hrs. It's safe for inside use as well as external use, and can protect your basement in many ways.
